LIGHTING ATTACHMENT FOR ALARM-CLOCKS.

SPECIFICATION formingpart of Letters Patent No. 629,609, dated July 25, 1899. Application filed MitrchZ, 1899. Serial No. 707,472. (No model.)

To (1J/Z whom t Tim/y concern,.-

Be it known that I, CULLEN A. RoBEETsoN, of Milledgeville, in the county of Baldwin and State of Georgia, have invented a new and usefullmprovement in Lighting Attachments for Alarm-Clocks, of which the following is a specification.

My invention relates to Vthat class of devices by which a candle ora fire, or both, may be automatically lighted at a predetermined time,- the lighting being actuated from the alarm mechanism of a clock; and it has for its object an attachment for anvalarm-clock which will be sure to ignite the candle or tire at the set time and in a very simple manner.

The invention consists in the peculiar construction of the match-holder and tripping device andthe arrangement of the latter with respect to the winder for the alarm mechanism.

The invention further consists in certain details of construction and combination 0f the parts, which. I shall rst describe and then point out the novel features in the appended claims.

Reference is to be hadto the accompanying drawings, forming part of this specification, in which- Y Figure l is a face view of the clock. Fig. 2 is a rear elevation of the same. Fig. 3 is a plan view withparts broken away. Fig. 4 is an enlarged detail perspective view of the match-lighting devices, and Fig. 5 is an enlarged detail section illustrating the lockinglever and its tripping-arm.

The alarm-clock is held in a suitable casing A, so that its rear face B will come yiiush with the rear face of the casing, the gong C being fastened on such rear face, as shown, and its hammer projecting through an opening c. On the upper ledge ct 0f the casing is held a bracket D, with lower and upper plates d d',

respectively, and journaled to rotate about a vertical axis in said plates is the match-holder E, consisting, preferably, of a single piece of metal bent to form a shaft or axial portion e, doubled-up portion c', and rearwardly-'extending arm e2. Awasher e3 preferably ts around the axial portion or shaft c and rests upon the upper plate d'. A strong spring F has one end secured to the shaft e and encircles said shaft and has its. other end secured to a post e4. The tensionA of the spring F`is eX- erted to turn the match-holder E positivelythat is, with its rearward extension moving from the front of the plate d.' toward and against a stop in the form of an upright F', which latter prevents further movement of said holder. A curved plate G is attached in proximity to the match-holder by having lone end secured by a bolt to an arm e5, extending from the lower'plate d, and its other end bent around the rear ofthebracket and held thereto also by a bolt. On the curved plate G are formed clips g g g2,in which pieces of sandpaper H are adapted to be held for the purpose of contact with the head of a match I, secured in the holder E. The match is pref-y erably held by a case J, of suitable material, fitted over the doubled portion e of the holder and provided with an interior longitudinal groove J and a forward aperture J 2, through which the head of the match projects. A clamping-screw J3 fastens the match in its place.

Now it will be seen that when the matchholder rotates the match-head is scraped along the sandpaper in the curved holder andthe lighted match is presented beyond 'the holder. In order to prevent the rotation of the holder until a predetermined time, I mount a tripping deviceK on an arm k, extending upwardly from the lower plate d, the 'said trip lping device consisting of a lever c,'pivoted between its ends to swing in a vertical plane and whose free end is adapted to engage a recess e in the rearwardly-extending arm e2 of the match-holder, as shown, whereby the lever prevents the movement of the holder until tripped. The opposite end of the lever 7a has pivoted thereto a freely-swinging trip ping-arm 7a2, which is bent inwardly and hangs over the wing of the Winder L for the alarm mechanism for a purpose to be hereinafter dei scribed.

A fuse M is adapted to be held ina clip m, secured to the curved plate G near the upper edge thereof, the said fuse when in place ex tending in a slight curve above the ignition end of the match-holder across to a candle N, held in a candlestick N', attached to the rear face of the casing A. The other end of the fuse has a ball O, of combustible material, attached to it, as shown.

Now when the parts are in the position -to light the candle and the combustible ball.

It is to'be understood .that the ball is to be placed under the grate of a stove or in other suitable proximity to the same to kindle a-ire therein.

I-t is especially to be observed that after the lever It' has been tripped the tripping-arm will swing clear of the Winder by reason of its bent portion, as shown in dotted lines, thereby not interfering with the further and complete rotation of the said wing until the alarm mechanism has run down.

In preparing my fuse for ignition I wind it helically about a non-fusible wire P, so that the fuse will not drop after it hasbeen lighted and before it has accomplished its end.

'Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is*- l. An attachment for alarm-clocks consisting of a spring-actuated match-holder arranged to ignite a match, a tripping-lever loosely pivoted between its ends to swing in a vertical `plane and having one end arranged for engagement with said holder whereby to hold the latter in inoperative position and a bent tripping-arm pivoted to and depending from the other end of said lever and with its lower end normally resting in the path of rotation of the alarm-mechanism Winder wherebythe lever will be tripped when the Winder rotates and will then swing clear of the same, as and for the purpose set forth.

2. An attachment for alarm-clocks,compris ing a spring-actuated match-holder arranged to ignite a match, a device for holding said match-holder against the4 action ofsai d spring, and a tripping-arm connected with said device to trip the same to release the holder, said arm being pivotedV to swing freely and normally resting with its free end above and in the path of rotation of the alarm-mechanism winder, as set forth. t
